I should have guessed. That’s the procedure we have in our books about flying into BOG  and other high elevation airports. So basically, AA has the ability to do automatically what we have to perform manually.

There are probably several ways to handle the issue of high-altitude airports and pressurization logic, depending on aircraft age and model. In addition to having to deal with a non-standard pressurization/depressurization schedules, a means has to exist to disable cabin altitude alarms, and in some cases, automatic passenger mask deployment.
